I have an error that says "OnItemClickListener cannot be resolved to a type" when I enter this code in:
package com.funkystudios.android.facts;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class activity2 extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] Facts = getResources().getStringArray(R.array.Facts_Array);
setListAdapter(new ArrayAdapter<String>(this, R.layout.list, Facts));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeTex开发者_StackOverflow中文版t(getApplicationContext(), ((TextView) view).getText(),
Toast.LENGTH_SHORT).show();
}
});
}
}
It occurs right at the "lv.setOnItemClickListener(new OnItemClickListener() {". I'm not sure what I'm doing wrong.
I figured it out, I had imported the wrong items!
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
That is what it should look like.
I have an error that says"The method setOnTouchListener(View.OnTouchListener) in the type View is not applicable for the arguments (new CarouselAdapter.OnItemClickListener(){})"
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Carousel carousel = (Carousel)findViewById(R.id.carousel);
carousel.setOnItemClickListener(new OnItemClickListener(){
LinearLayout layout = (LinearLayout) findViewById(R.id.LinearLayout01);
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
//String[]img = getResources().getStringArray(R.array.entries);
//img.setDrawingCacheEnabled(true);
//img.setOnTouchListener(this);
//@Override
public void onItemClick(CarouselAdapter<?> parent, View view,
int position, long id) {
Toast.makeText(MainActivity.this, "Position=" + position, Toast.LENGTH_SHORT).show();
view.setDrawingCacheEnabled(true);
view.setOnTouchListener(this);
}
});
